The rest of the programme consisted of eight more lightly armoured cruisers, a reduced number of destroyers and an increased number of submarines. In the 1914–15 Estimates three more battleships of the _Royal Sovereign_ class--to be named _Renown_, _Repulse_, and _Resistance_--were provided for, also a sixth ship of the _Queen Elizabeth class_, which was provisionally named _Agincourt_. The participation of any of these in the war is very improbable. The other vessels of the programme were four lightly armoured cruisers, twelve destroyers and an unstated number of submarines. When war broke out three battleships building in British Yards--two for Turkey and one for Chili--were taken over by the British Admiralty. Details of these are as follows:-- ==========================+===============+============================== Name. | Displacement. | Armament. --------------------------+---------------+------------------------------ _Agincourt_ | | (ex-_Sultan Osman I_) | 27,500 | 14--12in., 20--6in.; 3 tubes. | | _Erin_ | | (ex-_Sultan Rechad V_) | 23,000 | 10--13.5, 16--6in.; 3 tubes. | | _Canada_ | | (ex-_Almirante Latorre_)| 28,000 | 10--14in., 16--6in.; 4 tubes. ==========================+===============+============================== There were also taken over three Brazilian armoured gunboats--renamed _Humber_, _Severn_, and _Mersey_--of 1,200 tons each, carrying two 6-inch guns forward and two 4.7-inch howitzers aft. The speed is about 11½ knots, and early use was made of these vessels on the Belgian coast shortly after the outbreak of war. In addition to the above, two large Chilian destroyers building at Cowes were taken over and renamed _Broke_ and _Faulknor_. A variety of other vessels were likewise incorporated into the British Fleet, liners (to act as auxiliary cruisers), trawlers (to act as mine sweepers), plus various hospital ships, transports, and so on and so forth. Roughly, from 25 to 33 per cent. of the British Mercantile Marine came to be used in some way or other by the Admiralty--to say nothing of innumerable private yachts and motor boats. The destroyers of the period have not materially differed from their predecessors of the Dreadnought era, save for the adoption of two, and subsequently three, 4-inch guns in the armament, instead of one. Submarines and aerial craft are dealt with in a separate chapter. * * * * * At and about the year 1912, the “super-Dreadnought” may be said to have reached its apotheosis.
